Global Ship Lease (GSL) is expanding its reefer fleet in a containership market that is reaching highs not seen in years.
New York-listed GSL has bought four 5,470-teu panamax reefer boxships with an average age of about 11 years for $148m.
The Baltic Exchange's Freightos Container Index has almost quadrupled over the past year to 6,183 points on Wednesday.
GSL said the vessels will begin three-year fixtures to "a leading liner operator" upon delivery in the third quarter.
